Koyunlarda bazı kaba ve yoğun yemlerin naylon kese yöntemiyle kuru ve oganik madde yıkımlanabilirliklerinin ve enzim tekniği ile kuru ve oganik madde sindirilebilirliklerinin saptanması

Bu çalışma yaygın olarak kullanılan ruminant yemlerinin in vitro enzim ve in situ yöntemle kuru ve organik madde sindirimlerini ortaya koymak amacıyla planlanmıştır. Bu amaçla araştırmada 45 yem örneği (her birinden beş adet olmak üzere yulaf, arpa, mısır, buğday, yonca, çayır otu, soya küspesi, pamuk tohumu küspesi, ayçiçeği tohumu küspesi) kullanılmıştır. Yem örneklerinin kuru madde ve organik madde sindirilebilirlikleri enzim tekniği ile tespit edilmiştir. Yemlerin kuru ve organik madde yıkımlanabilirliği naylon kese tekniği ile bulunmuştur. Yulaf, arpa, mısır, buğday, yonca, çayır otu, soya küspesi, pamuk tohumu küspesi ve ayçiçeği tohumu küspesinin kuru ve organik madde sindirilebilirliği sırasıyla %54.00, %60.65, %69.38, %61.39, %44.19, %51.21, %67.26, %55.50 ve %61.69; %53.48, %59.50, %67.62, %61.28, %43.27, %47.75, %66.95, %54.92 ve %58.68 olarak saptanmıştır. Yulaf, arpa, mısır, buğday, yonca, çayır otu, soya küspesi, pamuk tohumu küspesi ve ayçiçeği tohumu küspesinin 24 saatlik inkubasyonlarda kuru ve organik madde yıkımlanabilirliği sırasıyla %72.29, %78.60, %73.66, %79.89, %56.55, %51.3O, %68.13, %62.88, %62.70; %66.61, %77.78, %64.02, %78.61, %60.85, %59.63, %68.13, %61.80 ve %61.87 olarak tespit edilmiştir.

Determination of dry matter and organic matter degradability of some forages and concentrate feeds with nylon bag technique in sheep and its dry and organic matter digestibility with enzyme technique

This'study was planned to determine organic matter digestibility with in vitro enzyme and in situ methot of ruminant feeds used as widespread. For this aim, 45 feed samples (oat, barley, corn, wheat, lucerne, grass, soybeanmeal, cottonseed meal, sunflower meal; five of each) were used in the study. The dry matter and organic matter digestibilities of feed samples were determined with enzyme technique. The dry matter and organic matter degradabilities of feeds were determined with in situ techcnique. Dry matter and organic matter digestibilities of oat, barley, corn, wheat, lucerne, grass, soybean meal, cottonseed meal, sunflower meal were found to'be 54.00, 60.65, 69.38, 61.39, 44.19, 51.21, 67.26, 55.50 and 61.69 %; 53.48, 59.50, 67.62, 61.28, 43.27, 47.75, 66.95, 54.92 and 58.68 %, respectively. Dry and organic matter degradability in the 24 h incubations of oat, barley, corn, wheat, lucerne, grass, soybean meal, cottonseed meal, sunflower meal (five of each) by nylon bag technique were found to be 72.29, 78.60, 73.66, 79.89, 56.55, 51.30, 68.13, 62.88, 62.70 %; 66.61, 77.78, 64.02, 78.61, 60.85, 59.63, 68.13, 61.80 and 61.87 %, respectively.
